Peptide bonds
The amino acid components of peptides and proteins are linked together by amide bonds see p. 60 between a-carboxyl and a-amino groups. This type of bonding is therefore also known as peptide bonding. In the dipeptide shown here, the serine residue has a free ammonium group, while the carboxylate group in alanine is free. Since the amino acid with the free NH3 group is named first, the peptide is known as seryl alanine, or in abbreviated form Ser-Ala or SA. Like all acid-amide bonds, the peptide...

A large number of metabolic pathways are available for amino acid degradation, and an overview of these is presented here. Further details are given on pp. 414 and 415. A. Amino acid degradation overview 3 During the degradation of most amino acids, the a-amino group is initially removed by transamination or deamination. Various mechanisms are available for this, and these are discussed in greater detail in B. The carbon skeletons that are left over after deamination undergo further degradation...

The lipids are a large and heterogeneous group of substances of biological origin that are easily dissolved in organic solvents such as methanol, acetone, chloroform, and benzene. By contrast, they are either insoluble or only poorly soluble in water. Their low water solubility is due to a lack of polarizing atoms such as O, N, S, and P see p. 6 . Lipids can be classified into substances that are either hydrolyzable i. e., able to undergo hydrolytic cleavage or nonhydrolyzable. Only a few...

A. Structure of phospholipids and glycolipids 3 Fats triacylglycerol, 1 are esters of glycerol with three fatty acids see p. 48 . Within the cell, they mainly occur as fat droplets. In the blood, they are transported in the hydrophobic interior of lipoproteins see p. 278 . Phospholipids 2 are the main constituents of biological membranes see pp. 214-217 . Their common feature is a phosphate residue that is esterified with the hy-droxyl group at C-3 of glycerol. Due to this residue,...
