AGRICOLA -- Guide to Subject Indexing

signpost for indexer usage of the singular vs. plural form of these descriptors. This isillustrated in some of the sample titles below.The plural form is used in a variety of contexts when the specific proteins from asource are studied. Some examples of specific proteins are albumen andovomacroglobulin from eggs, casein and alpha-lactalbumin from milk, and gluten andgliadin from cereals. In some cases when the protein is named, you will find that aspecific descriptor is available for it. The plural form of the descriptor is used when thearticle is concerned with the composition of a protein from a given source.Sample titles:ooooooTwo proteins from celery isolated by liquid chromatography.Detection and quantitation of cereal protein in foods using specific enzymelinkedmonoclonal antibodies.Quantitative analysis of gelation in egg protein systems.Nutritional and functional properties of egg proteins.Development of a new fractionation method for milk proteins.Blood protein variations within and between horse populations.The singular form of the descriptor is used when the article is concerned with theprotein as a general nutrient from a given source, such as the contribution of egg proteinto the American diet, cereal protein as a component of chicken feed, or oat protein as agood source of essential amino acids. The singular form is used when protein isdiscussed as total protein or protein content from a source.Sample titles:ooooooEffect of substituting peanut meal in part for animal protein in laying mash onegg production, hatchability, and livability of chicks.Effect of feeding different animal proteins on the trace-element composition ofbroiler droppings.Utilization of concentrates of various cereal proteins in baked products inCentral America.Utilization and requirement of egg protein in Japanese women.Substitution of milk protein with soyflour or meat-solubles in calf milkreplacers.The use of decolorized blood protein in a cheese spread.(If both protein content and protein composition are studied in the same article, it couldbe appropriate to use both singular and plural descriptors.)In particular, use great care before applying the singular form BLOOD PROTEIN. Theoverwhelming majority of articles in AGRICOLA should be indexed with BLOODPROTEINS; most of these articles will be in the context of veterinary medicine orhuman nutrition.
