Haemoglobin is a protein which is found in red blood cells and is responsible for carrying oxygen from the lungs to the rest of the body and transporting carbon dioxide back to the lungs.

Haemoglobin is an iron-containing protein found in the red blood cells of mammals. It carries oxygen (O) from the lungs and transports it to the tissues in the body. Haemoglobin is also the protein which gives red blood cells their red colour.

Haemoglobin is a protein present in our blood, giving it it's red colour. It facilitates oxygen delivery, by allowing oxygen to bind to it, with the assistance of the iron atom contained within it. It can also carry carbon dioxide back to the lungs.

Keratin is a fibrous protein that provides structural integrity to the hair, skin and nails. Found mostly in epithelial cells (lining the surface of the body). Its functions include protection & renewal of epithelial cells, strengthening & repairing hair and maintaining elasticity of skin.

Haemoglobin is an iron-containing protein in red blood cells responsible for transporting oxygen from the lungs to tissues and returning carbon dioxide from tissues to the lungs. It forms a reversible bond with oxygen, allowing efficient gas exchange. In its oxygenated state, it is called oxyhaemoglobin and appears bright red; in its deoxygenated state, it is purplish-blue.

Immunoglobulins are glycoprotein molecules produced by plasma cells in response to antigens. They function as antibodies, binding to specific antigens to neutralise pathogens or mark them for destruction.

Rhodopsin is a light-sensitive receptor protein in rod cells of the retina. It plays a crucial role in dim light vision by converting light into an electrical signal, initiating the visual phototransduction pathway. Mutations in the RHO gene can lead to retinal diseases such as retinitis pigmentosa and night blindness.

Collagen is the most abundant protein in the human body, constituting about 30% of total protein. It serves as the primary building block of skin, muscles, bones, tendons, ligaments, and other connective tissues. Collagen provides structural support and strength to these tissues.

Keratin is a fibrous structural protein found in hair, nails, skin and epithelial cells. It provides mechanical strength and protection to these tissues, serving important structural and protective functions, particularly in the epithelium.

Lipase: Lipase is an enzyme that catalyses the hydrolysis of ester bonds in lipids, converting triglycerides into glycerol and fatty acids. It is essential for the digestion and absorption of dietary fats.
Pepsin: Pepsin is a proteolytic enzyme secreted in the stomach as pepsinogen, its inactive precursor. It is activated by stomach acid and breaks down proteins into smaller peptides, aiding in protein digestion.
Insulin: Insulin is a hormone produced by the pancreas that regulates blood glucose levels. It facilitates the uptake of glucose into cells for energy production and storage, playing a vital role in metabolic processes.

Hemoglobin is an iron containing protein in red blood cells that is responsible for transporting oxygen from the lungs to tissues throughout the body and carrying carbon dioxide back to the lungs for expulsion.

Immunoglobin also known as antibodies, these glycoproteins are produced by plasma cells and play a crucial role in the immune system by binding to antigens and neutralizing harmful pathogens.

Haemoglobin is a two-way carrier respiratory carrier, carrying oxygenated blood from the lungs to the tissues, and facilitating the return of deoxygenated blood from all cells/tissues to the lungs. The Heme group contains Fe 2+ which is responsible for oxygen binding to be transported as oxyhaemoglobin around the body.

Rhodopsin is a light-sensitive receptor protein found in the retina’s rod cells rhodopsin is essential for vision in dim light. It converts light into electrical signals that are transmitted to the brain.

Immunoglobulin is a glycoprotein that is highly specific and secreted in large amounts by plasma cells in response to disease-causing toxins, pathogenic antigens, etc. being introduced to our bodies.

Rhodopsin is a pigment-containing sensory protein which converts light into an electrical signal, and is found in a wide range of organisms. In many "seeing-animals", it is required for vision in dim light and is located in the retina of the eye, specifically in the tightly packed disks that make up the outer segment of the retina's photoreceptive rod cell tightly packed disks that make up the outer segment of the retina.

Haemoglobin is a protein in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues to the lungs. It binds oxygen in areas of high concentration and releases it where it is needed, supporting cellular respiration and overall energy production.

Collagen is a fibrous protein which provides mechanical and biological support for virtually all human tissues in the extracellular matrix. Depending on the mineralisation, collagen tissues may be rigid (bone) or compliant (tendon) or have a gradient from rigid to compliant.

Immunoglobulin is a protein produced by the immune system to identify and neutralise foreign invaders such as bacteria, viruses, and toxins. Playing a key role in immune defence.

Rhodopsin is a light-sensitive protein found in the rod cells of the retina. It plays a crucial role in vision, especially in low-light conditions, by converting light into electrical signals that the brain can interpret. When light hits rhodopsin, it changes shape, triggering a cascade that enables night vision.

Hemoglobin is an iron-containing protein present in red blood cells that picks up oxygen from the air we breathe and delivers it everywhere in the body. It's the hemoglobin that gives blood its red color too. After transporting oxygen, it also becomes a magnet for carbon dioxide (waste product of cell) and gives it back to the lungs.

Haemoglobin is a protein in red blood cells that binds to oxygen in the lungs and releases in in tissues. On the return, it binds to carbon dioxide in tissues, bringing it to the lungs to be expelled.
