Explanation / Answer

Globular protein - Soluble in water, acid, alkalis and salts. These proteins are highly branched and crosslinked. The polypeptide chains ( amino acid sequence) of this protein held together by crosslinked groups and found in aggregate state and folded to form three dimensional structure by weak non covalent bonds.

Steroid - It is a simple lipid contain no fatty acids.It has profound biological activity in hormones and highly fat soluble biomolecules. It is major class of non saponifiable lipids (not forming esters) derived from five carbon building blocks.

Beta carotene - Carotenoids are higher terpenes, a class of tetra terpene hydrocarbons. An important carotinoid is beta carotene, is a hydrocarbon precursor of vitamin A.

Ribozyme - Ribosomes are made up of rRNA and protein and are present in the site of protein synthesis. Ribozymes are enzymes in ribosomes functions as catalytic reaction

Purine - Purines are organic compounds containing two condensed heterocyclic rings, pyrimidine ring and imidazole ring. It does not occur naturally but it is a synthetic compound.

Pyrimidine - In this compound the parent heterocyclic nucleus is pyrimidine. Heterocyclic possess 2 nitrogen atoms in 1:3 position gives the basicity. Pyrimidine bases in nucleic acids are cytosine, uracil and thymine. It is crystalline and synthetic compound.

Uracil - It is 2-6-dihydroxy pyrimidine, It is present normally in ribonucleic acid but only rarely in DNA

Adenine - otherwise 6-amino purine, is a purine derivative

Thymine - Thymine is pyrimidine derivatives, otherwise 5-methyluracil present in Deoxyribonucleic acid (DNA) but not usually in Ribonucleic acid (RNA)

GTP- Protein synthesis involves three steps initiation, elongation and termination. Each step involved with different proteins and use of energy in the form of guanosine triphosphate (GTP)

c AMP- cyclic- Adenosine mono phosphate

Phosphodiester linkages - Nucleotide is the combination of nitrogen base (purine or pyrimidine), deoxy sugar and phosphoric acid. The individual mononucleotides linked to one another by phosphate bridges. The phosphate linked to 3' carbon of the deoxy sugar of one nucleotide to the 5' carbon deoxy sugar of neighbour to form phosphodiester linkages.

Ketone - Derivatives of fatty acid metabolism

Sulphydril group - These are SH groups (Thio groups) involved in the linkage of poly peptide chains

Condensation reaction - Dehydration reaction, two large molecules combine to form single molecule.
