1) Glycerol: trihydroxy alcohol
2) Fatty acid: carboxylic acid, long aliphatic chain.
Triglycerides can be of two types: SATURATED or UNSATURATED]]> 2018-10-26 16:00:25 UTC https://padlet.com/giulya2000/1v36oqymaksn/wish/297461056 Saturated giulya2000 https://padlet.com/giulya2000/1v36oqymaksn/wish/297505718 Animal triglycerides, fpr example, are called fats too, and they are mainly made up of staurated fatty acids chains. They also contain trans-unstaurated fatty acids. Trans-unsaturated fatty acid are composed by rigid and straight chains. 
Saturated fatty acids are made up of chains that pack together closely. This causes that fats have higher melting and boiling points. They're also solid at room temperature. ]]> 2018-10-26 17:28:33 UTC https://padlet.com/giulya2000/1v36oqymaksn/wish/297505718 Unsaturated giulya2000 https://padlet.com/giulya2000/1v36oqymaksn/wish/297508624 Plants triglycerides, for example, are called oils too, and they are mainly made up of unsaturated fatty acids chains, that are generally in cis- configuration. Cis- configuration implies that the carbon chain extends from the same sid of the double bond. This kind of chains pack together poorly. So they have lower melting and boiling points, and they are liquid at room temperature.]]> 2018-10-26 17:34:08 UTC https://padlet.com/giulya2000/1v36oqymaksn/wish/297508624 Exercise number 1 page giulya2000 https://padlet.com/giulya2000/1v36oqymaksn/wish/305672408 Proteins and related functions]]> 2018-11-18 16:26:04 UTC https://padlet.com/giulya2000/1v36oqymaksn/wish/305672408 Enzymatic (biological catalysts breaking down particular bonds, such as macromolecules in food, so they can be easily absorbed) giulya2000 https://padlet.com/giulya2000/1v36oqymaksn/wish/305672512 E.g.
